# RAG Architecture From Naive Pipelines to Agentic Retrieval - Production RAG now relies on multi-stage retrieval, hybrid search, and reranking. - Agentic RAG adds control loops so the model decides when and how to retrieve. - GraphRAG improves multi-hop retrieval through entity and relationship structure. - Hallucinations can persist even when retrieval succeeds. - Chunking strategy materially changes retrieval quality and cost. - Runtime guardrails and centralized policy enforcement matter for autonomous agents. ## **Building Multi-Stage Retrieval Pipelines** Production RAG has moved beyond
